The messages are for my enp4s0, but it has no IP address. This is via my
iptables setup. I assume this is happening because br0 (that I would
normally
NAT for me) is not up:

I think you probably had configured lan1 and lan2 in a specific
firewall "zone" but now that the interfaces aren't being renamed, they
aren't in a zone and don't have rules. If you are going to give up on
renaming, you'll want to put those interfaces in the appropriate
firewall zone.
I found these in my log files, they look very relevant to my problem,
but I
haven't figured out why they are busy:
...

"ip" is your friend. To rename an interface it must be down.
"ip link set enp4s0 down"
"ip link set enp4s0 name eth0"
"ip link set eth0 up"
Note that when you take an interface down it disappears from the routing
tables. You'd again use "ip" to add the route. This example adds the
default route.
"ip route add default via <GATEWAY_IP> dev eth0"
Note that eth0 was used for example purposes. You'd use "lan1" or "lan2".
